[PATCH 3/3] Make client behavior configurable

[Lucas Meneghel Rodrigues <lmr@redhat.com>]

Right now autotest will drop caches between:

    * Test executions
    * Same test iterations

This change turns those into configurable options on
global_config.ini. The default values were added on the
previous patch.

2nd attempt: Now global config support for stand alone client
runs was added. Everything should work now.
